In some of the test code in Interpolations.jl, I’ve stumbled over the macro Base.Test.@inferred. I took a look at the source code <https://github.com/JuliaLang/julia/blob/e22233ece2516fee7212538a618a3c72a6f84d0f/base/test.jl#L161-L172> but didn’t get much wiser. Also, there’s no documentation in the doc system, so ?@inferred in the REPL doesn’t give anything at all.
What does @inferred do? What does it return? // T
